WILLY PIETSUH, OF PULSNITZ, GEREANY ZIP 03 L IGHTNING FASTENER Application filed November 19, 1930, Serial No. 496,710, and in Germany November 18, 1929.

This invention relates -to an improvement in zip or lightnin fasteners for clothes, boots, bags and the li e. fasteners of this type which consist of-two ribbons, edged with metallic fastening links,

were not completely covered and the rib-- bons, on bending the fastener, were liable to crease, thereby presenting a bad appearance, not considering that cotton ribbons retain dirt. Leather or rubber stri s are at best only suitable for boots, not orclothes for whlch woven strips should be used. Leather strips do not close tight, but show the same inconveniences as ribbons.

To avoid these drawbacks the covering ribbons according to my invention consist of fringed plushbraid arranged upon the ribbons of the zip fastener. arranged in such a manner that the fringed or plush portionsof these braids cover the metal members of the fastener and by meeting each other in the middle line hide all the metal elements of the fastener. At the same time an adornment of the articles .provided with my new fastener is effected.

To avoid undesired. separation of the fringed edges of the braid the handle for operating the slider consis's of a thin pin or chain which is guided in a groove of the slider by meansof a small plate inserted in the said roove. The free end of the pin or chain may e provided with a small ball or someother means for catching hold of thepin or chain. so The whole zip fastener hereby acquires a nicer appearance; the covering edges. of the fringed or plush braids are only slightly bent aside by the new handle.

The invention is illustrated by way of example in the annexed drawing in which Fig. 1 is a plan view of the fastener in closed condition;

Fig. 2 is a vertical cross-section; Fig. 3 is a plan view of the slider on an en'- larged scale;

The well-known The braids are Fig. 4 is a cross-section of then of the slider folowing the line Fi 3.

ig. 5 .is a diagrammatic cross-sectional view showing a modification.

Fig. 6 shows the combination of the parts shown separately in Figures 4 and 5.

.a is the the ribbon of the fringed braid which is sewed on the ribbons of the zip fastener. b, 1) indicate the lateral fringed or plush edges of the braids a, a. The edges of the ribbons c are thickened in the wellknown manner to form small rolls e e, to which the metallic fastening members at, d are secured. f is the upper shield of the slider which carries two- L-shaped bars 9, g forming a guide for the handle of the slider.

IV of This handle consists of a plate It encompassed by the bars g, g. In the center of the plate h a thin pin or chain 2' is' fixed carrying at its end a small ball k or other thickening device, the pin or chain passin between the bars 9 g and the fringed brai s b, b. This handle may be moved to and fro from one end ofthe slider to its other end which is important for easily operatingthe zip fastener.

The above described fastener has the draw back that the hairs of the fringed braid may possibly be caught between the slider and fastening members guided therein.

.By further investigations I have foundthat the protecting braids permanently retain their action even when usmg' a normal slide:

by inserting an intermediary layer, for instance, in the form of a flat tape or braid beper shield tween the fringed braid and the base ribbon of the fastener, thereby from the beginning raising the level of the fringed braid above the base ribbon.

This modification is illustrated in Figs. 5 and .6 of the drawings. 7 is the slider, c the base ribbon of the fastener, to which the lock-. ing members d are attached. Z is the protecting tape and a, b the fringed braid. Between the base ribbon c and the protecting tapel is the intermediary layer m. The latter as well as the protecting tape and the fringed braid are sewed upon the base rib- .bon c. V

greatly bent position (the fringed braid being on the convex side).

' I claim I 1. A zi or lightning fastener comprisinga pair 0 opposed ribbons, fastening members secured to said ribbons, a slider movable on said members for causing the same to interlock or disengage from each other and fringed braids secured to the opposed ribbons and covering the fastening members to conceal the same from View.

2. A zip or lightning fastener comprising a pair of opposed ribbons, fastening members secured to said ribbons, a slider movable on said members for causing the same to interlock or disengage from each other, fringed braids secured to the opposed ribbons and covering the fastening members to conceal the same from view, a pair of L-shaped .bars on the said slider forming a guiding groove,

' a plate guided in the said groove, and a narrow handle secured to the said plate.

3. A zip or lightning fastener comprising a pair of opposed ribbons, fastening members secured to said ribbons, a slider movable on said members for causing the same to interlock or disengage from each other, fringed braids secured to the opposed ribbons and covering the fastening members to conceal the same from view, a pair of L-shaped bars on the said slider forming a guiding groove, a plate guided in the said groove, anda narrow handle secured to the said in a thickening portion. 7

4. A zip or lightning fastener comprising a pair of opposed ribbons, fastening members secured to said ribbons, a slider movable on said members for causing the same to interlock or disengage from each other, fringed braids secured to the opposed ribbons and covering the fastening members to conceal the same from view, a pair of L-shaped bars on the said slider forming a guiding groove, a plate guided in the said .groove, and-a narrow handle secured to the said plate and end-.

ing in a small ball.

5. A zip or lightning fastener comprising a pair of opposed ribbons, fastening members secured to said ribbons, a slider movable on said members for causing the same to interlock or disengage from each other, a pair of tapes overlapping the space between the said slider and ribbons, intermediary layers between the said tapes-and ribbons, and fringed braids'secured to the'opposed ribbons and covering the fastening members to conceal I 1 the same from view.
